Definitions

  • Embodiments of the present invention relate to a holder for a cylindrical member and a method for operating the holder.
  • a cylindrical element for example, a steel wire, rope or cable
  • supports with lighting equipment or other stage-related element are often attached by means of hanging steel wires or by means of hanging cables.
  • cable holders or generally holding devices are typically used.
  • the diameters of the cables or wires may sometimes vary considerably, with the conventional cable holders typically being designed for only one (cable) diameter or diameter range. This has the consequence that other cylindrical elements with different diameter can not be maintained or that damage, such. Notches are unavoidable at these.
  • the holding properties in conventional holding devices depend heavily on the material combination used between the holder and the cylindrical element to be held. Therefore, there is a need for an improved approach.
  • the patent specification describes DE 41 04 896 C1 a device for catching a drill string.
  • the device comprises a trapping frame with an abutment roller and a pivotable roller-type linkage clamping element.
  • this linkage clamping element which has a clamping groove, the drill string is clamped.
  • Such a device is designed for maximum clamping force, since the drill pipe is typically not flexible. In this respect, when clamping a fixed linkage, you do not have to pay attention to a material-saving grip.
  • Object of the present invention is to provide a holding device which is flexible and has optimized ergonomic properties.
  • Embodiments of the present invention provide a holding device for a cylindrical member such as a cable.
  • the holding device comprises a main body and two clamping members rotatably mounted on the main body, each having an at least partial cylinder segment portion with a radial clamping groove (eg, with a semicircular or V-shaped shape).
  • the clamping elements are arranged relative to one another such that a clamping region is formed between the radial clamping grooves of the two cylinder segment sections.
  • the holding device is designed to vary a cross-sectional area of the clamping region upon rotation of the clamping elements.
  • a holding device can be made flexible with respect to the (cylindrical) elements to be held, when the cross-sectional area of the clamping region is variable. Due to the variation of the cross-sectional area, the clamping or holding of the element to be held also takes place at the same time.
  • a gentle clamping grip of the element to be held can be achieved if the variation of the cross-sectional area occurs during a rotational movement of (for example roller-shaped) clamping elements or two (tangentially opposite) cylinder segment sections of the clamping elements, wherein a clamping region is formed between the two cylinder segment sections.
  • the background to this is that such sharp edges in the clamping area (which can lead to damage) can be avoided.
  • Each cylinder segment portion also has a radial clamping groove to increase the engagement surface with the cylindrical member.
  • the variation of the cross-sectional area is achieved in that the clamping grooves, by means of which the engagement with the cylindrical element is produced, each have a tapering region extending along the respective cylinder segment section and tapering with respect to the depth and / or width of the clamping groove.
  • the tapering region of the one clamping groove opposite to the opposite clamping groove may be formed such that the cross-sectional area of the clamping region is varied (reduced or enlarged) in the case of an opposite rotation of the two clamping elements.
  • the variation can also take place in that the rotatably mounted on the main body clamping elements are mounted with the cylinder segment sections eccentrically relative to the main body, so that the distance between the two clamping elements in a (counter-rotating) is also variable.
  • the rotational directions of the clamping elements can be designed such that it extends counter to a force direction of the male force of the cylindrical member, with the result that the clamping force is enhanced by the action of force of the cylindrical member or on the cylindrical member.
  • the holding device has at least one spring, which is designed to move or rotate the two or at least one of the clamping elements into a position with a reduced cross-sectional area.
  • the two or at least one of the clamping elements are operable from the outside, so that they can be opened.
  • the two clamping elements e.g. like gears, engage each other so that movement of one clamping element also causes movement of the other clamping element. Consequently, it is thus possible to operate only the one clamping element so as to move both clamping elements in an open position.
  • a further embodiment relates to a method for operating the holding device with the step of rotating the clamping elements, so that a cross-sectional area of the clamping area is varied.
  • Fig. 1 shows a holding device 10 for a cylindrical member 12, such as a rope or cable.
  • the holding device 10 comprises a main body 14 and two clamping elements 16 a and 16 b, which are rotatably mounted on the main body 14.
  • the two clamping elements 16a and 16b are designed in this embodiment as a rotary rollers, but generally have at least one partial cylinder segment portion 18a and 18b, which need not necessarily extend over the full circumference of the respective clamping member 16a and 16b.
  • radial clamping grooves 20a and 20b are introduced, which serve to make the engagement with the cylindrical member 12 and to hold this in the desired position.
  • the clamping grooves 20a and 20b are opposite each other, so that between them a cross-sectional area, for example a round or approximately round cross-sectional area, is formed, which forms the clamping area 22.
  • the cross-sectional area 22 in the closed position is set to be smaller than or at least equal to the cross-sectional area of the cylindrical member 12 to cause jamming (wedging action) between the clamping portion 22 and the cylindrical member 12 ,
  • the shape of the two clamping grooves 20a and 20b may be preferably adapted to the shape of the cylindrical member 20 so as to produce a maximum contact surface with the cylindrical member 12 to be held.
  • each of the two clamping grooves 20a and 20b may have a semicircular or V-shaped form.
  • the clamping region 22 is formed between the two rotor-shaped clamping elements 16a and 16b and between the two cylinder segment sections 18a and 18b, whereby the cylindrical element 12 to be clamped is perpendicular through the clamping region 22 defined by the clamping grooves 20a and 20b extends, so that the clamping elements 16a or 16b are arranged tangentially with respect to the central axis of the cylindrical member 12 to be held.
  • the cross-sectional area 22 is made variable.
  • the two clamping elements 16a and 16b which finally determine the cross-sectional area 22 via the clamping grooves 20a and 20b, are rotatably mounted relative to the main body 14.
  • the cross-sectional area 22 is varied by the two clamping grooves 20a and 20b approach or remove from each other.
  • the variation of the cross-sectional area 22 can take place on different mechanisms, wherein two mechanisms are explained below by way of example.
  • the two clamping elements 16a and 16b are mounted eccentrically relative to the main body 14, so that upon rotation of the two clamping elements 16a and 16b, the distance between the cylinder segment sections 18a and 18b and thus the cross-sectional area 22 changes.
  • the cross-sectional area 22 decreases as the two clamping members 16a and 16b are oppositely directed in a second direction (see vectors 23a and 24b) 23b) are rotated.
  • the direction vectors 23a and 23b are oriented opposite to the direction vectors 24a and 24b.
  • both a thin wire rope and in the extreme case a thick rope (ship traffic jam) can be clamped with the same holding device 10.
  • the variation of the cross-sectional area 22 is effected by the two clamping grooves 20a and 20b tapering along the respective cylinder segment portions 18a and 18b.
  • each clamping groove 20a and 20b has a tapering region 20a and 20b extending along the respective cylinder segment section 18a and 18b. Over this tapering portion 20a and 20b depth and / or width of the clamping grooves 20a and 20b are reduced.
  • the two tapering regions 20a and 20b are oriented in opposite directions, so that, in the case of an opposite rotation in the first direction (see arrows 24a and 24b), an enlargement of the cross-sectional area 22 continues, whereas with an (opposite) rotation in the second direction (cf.
  • the taper regions 20a and 20b may also be described by way of taper vectors extending along the cylindrical surface segments 18a and 18b.
  • the taper vectors for the two taper portions 20a and 20b corresponding to the rotation vectors 23a and 23b.
  • the two tapering vectors 23a and 23b extend in the clamping region 22 tangentially to one another, and also tangentially to the cylindrical element 12th
  • This arrangement has the advantage that the two clamping elements 16a and 16b can be coupled to one another in a rotational manner via the cylinder segment sections 18a and 18b (see contact point 15), so that rotation of the one clamping element 16a (eg along the vector 23a) an (opposite) rotation of the other clamping element 16b (eg along the vector 23b) leads.
  • This coupling can, for example, be frictionally engaged or in that the cylinder segment sections 18a and 18b are formed as meshing pairs of gears.
  • the gears 18a and 18b or generally the engaging portions 18a and 18b serve to ensure synchronous travel of the two clamping members 16a and 16b such that the taper of the grooves 20a and 20b at the point of contact 15 where the two rollers 16a and 16b meet , always the same.
  • synchronizing the rotational movements of the two clamping elements 16a and 16b one-handed operation is made possible or facilitated, since only one of the two clamping elements 16a or 16b is used to open or close the clamping region 22 (or in general to vary the cross-sectional area 22) is required.
  • the direction of the two tapering vectors 23a and 23b is chosen such that, when the retaining element 10 is fastened to the cylindrical element 12, which for example hangs down vertically, it is fastened to the holding device 10 due to the gravity of the holding device 10 itself Load to a rotation of the clamping member 16a and 16b along the rotation vectors 23a and 23b comes, which leads to a reduction of the cross-sectional area 22 and thus to an increase of the clamping force. As a result, a kind of self-locking of the holding device 10 takes place.
